The pathogenic gram-positive bacterium Clavibacter michiganensis subsp. michiganensis (Smith) Davis et al. is the most harmful bacterium to tomatoes in many countries with a cooler climate. Multilocus sequence analysis was performed on five housekeeping genes (bipA, gyrB, kdpA, ligA, and sdhA) and three virulence-related genes (ppaA, chpC, and tomA) to determine evolutionary relationships and population structure of 108 C. michiganensis subsp. michiganensis strains collected from Turkey between 1996 and 2012. Based on these analyses, we concluded that C. michiganensis subsp. michiganensis in Turkey is highly uniform. However, at least four novel C. michiganensis subsp. michiganensis strains were recently introduced, possibly at the beginning of the 1990s. The singletons might point to additional sources or to strains that have evolved locally in Turkey.
致病革兰氏阳性细菌密歇根棒状杆菌亚种。密歇根（Smith）戴维斯等人。是许多气候凉爽国家对西红柿危害最大的细菌。对 5 个管家基因（bipA、gyrB、kdpA、ligA 和 sdhA）和 3 个毒力相关基因（ppaA、chpC 和 tomA）进行了多位点序列分析，以确定 1996 年至 2012 年间从土耳其收集的 108 株 C. michiganensis subsp。密歇根亚种的进化关系和种群结构。基于这些分析，我们得出结论，土耳其的 C. michiganensis subsp。密歇根亚种非常均匀。然而，最近至少引入了四个新的 C. michiganensis subsp。密歇根亚种，可能是在 90 年代初。单倍型可能指向其他来源或在土耳其本地进化的菌株。
